Last year, I reviewed U4 Quad Hybrid, an Android TV box powered by Hisilicon Hi3796M quad core Cortex A7 processor and with a combo DVB-T2/C + DVB-S2 tuner. with digital TV tuner. It worked pretty well, except for a few bugs here and there, the processor is not the most powerful, and video output & decoding is limited to 4K @ 30Hz. The company – Shenzhen Vivant Technology – is now back with a new model called U5 PVR powered by a more powerful Hisilicon Hi3798C V200 quad core Cortex A53 processor with fast interfaces like USB 3.0, SATA, and Gigabit Ethernet, as well as support for 4K @ 60Hz via a HDMI 2.0a interface. There are actually three variations of U5 PVR with Deluxe/Slim/Normal models, and the company sent me U5 PVR Deluxe model for review. As usual, after listing the specifications, I’ll start the review by checking out […]
Yundoo Y8 (Rockchip RK3399) TV Box Review – Part 1: Unboxing and Teardown
Rockchip first unveiled RK3399 hexa-core processor at the beginning of 2016, but we had to wait longer than expected to get devices to play with. The first retail product based on the processor is really Samsung Chromebook Plus, and we only saw a few TV boxes for pre-sale in January such as Yundoo Y8 or R-TV Box K99, and with the first shipments occurring in March. However, I’ve also noticed many companies postponed the launch of the RK3399 mini PC/TV box, and no company contacted me for review so far, so I had no rush because that probably means the boxes were not quite ready. But starting at the beginning of next month, more companies will start selling their model, and GearBest proposed to send me Yundoo Y8 model with 4GB RAm, 32GB flash, and decided to give it a go. In this first part of the review, I’ll only […]

Samsung & Amazon Introduce HDR10+ Standard with Dynamic Metadata & Tone Mapping
Most recent 4K Ultra HD televisions support high dynamic range (HDR) through standards such as HDR10, Dolby Vision, or Hybrid Log-Gamma (HLG). Samsung and Amazon have jointly introduced an update to HDR10 with HDR10+ that adds dynamic tone mapping & metadata. The companies describe the issues for HDR10′ static metadata as follows: The current HDR10 standard utilizes static metadata that does not change during playback despite scene specific brightness levels. As a result, image quality may not be optimal in some scenes. For example, when a movie’s overall color scheme is very bright but has a few scenes filmed in relatively dim lighting, those scenes will appear significantly darker than what was originally envisioned by the director. HDR10+ will be able to adjust metadata for each scene, and even for each frame, hence solving the issue of darker scenes. If you already own a Samsung TV with HDR10, it’s not […]
Karl’s Home Automation Project – Part 4: MQTT Bridge Updated to Use YS-IRTM IR Receiver & Transmitter with NodeMCU
In a previous article, I wrote about an MQTT bridge by 1technophile. I added a DHT temperature and humidity sensor as well as a light sensor. Previously it included a software decoder to decode the IR signal. I never did test the IR transmitter on the gateway, as I didn’t have the parts. But thanks to IC Station, who sent me over a small YS-IRTM hardware based decoder and NodeMCU that I am writing about today. I have replaced the software based version with the YS-IRTM module in the latest update. I found this project challenging. I admit I am a little weak in my programming skills. It was difficult to find documentation but I found a forum talking about this device and basics of how it works. When an IR code is recognized it sends 3 hex codes via serial connection on the transmit pin. To transmit, it expects […]
